To achieve homogeneous dispersion throughout the paint system, optimum efficiency and stable viscosity, it is advisable to produce an evenly mixed gelling agent stock paste before application. Using Borchi® Gen PB 60, low-concentration and high fine pastes with a stable viscosity and which are fully mechanically and chemically dispersed can be produced extremely quickly in a highspeed mixer. Properties Borchi® Gen PB 60 is excellently suited to manufacture of stock pastes from powdered inorganic gelling agents in organic solvents, e.g. white spirit, xylene, butyl glycol. The particular advantages in terms of performance of using this wetting and dispersing agent are as follows: -´very short dispersion and maturing time of highly concentrated pastes - homogeneous, easily usable, pumpable and scoopable gels - stable, non-skinning, corrosion-inhibiting pastes, even if stored for long periods in opened containers - can also be fully subsequently incorporated using high-speed mixer - excellent binder compatibility and no effect on drying properties of binders which dry physically or by oxidation. By virtue of its potent wetting effect, Borchi® Gen PB 60 can be added to the milling stock as a wetting and dispersing agent. At the same time, it has good antisettling action in pigmented systems. A surplus of wetting agent is to be avoided, however, to prevent a reduction in viscosity and phase separation. In conjunction with pyrogenic silica, Borchi® Gen PB 60 gives rise to thixotropic, high-viscosity gels which are particularly suited to use in structural and hammerfinish paints. Borchi® Gen PB 60 is usable in binders which dry physically by oxidation or in baking paints. Applications Borchi® Gen PB 60 can be used in the following binders: styrenated alkyd resins epoxy ester resins alkyd / nitrocellulose alkyd / urea / melamine silicone resins chlorinated and cyclized rubber vinyl resins PVC organosols / plastisols Mixing and addition rate This swelling agent can be used to produce low- to high-concentration pastes depending on the purpose for which they are required. By varying the ratio of gelling agents to the various dispersing agents, the consistency of the paste can be altered from thin and pumpable to solid. The inorganic swelling agent is added to the given solvent (e.g. white spirit, xylene or styrene) by stirring until evenly dispersed. The dispersing agent is then added. All concentrations are usable after maturing for 24 hours. Suggested paste formulation are as follows: a) pumpable paste 90.0 pbw solvent 7.5 pbw inorganic swelling agent 2.5 pbw Borchi® Gen PB 60 total 100.0 pbw paste b) standard paste 85.0 pbw solvent 10.0 pbw inorganic swelling agent 5.0 pbw Borchi® Gen PB 60 total 100.0 pbw paste c) highly concentrated paste 70.0 pbw solvent 20.0 pbw inorganic swelling agent 10.0 pbw Borchi® Gen PB 60 total 100.0 pbw paste The gloss, drying and hardness of the paints are unaffected by Borchi® Gen PB 60 at the recommended addition rates.
